This is an example for \texttt{mdwlist}, which makes it possible to
interrupt an enumerated list with standard text and continuing numbering
with following enumerate-layout. \texttt{mdwlist} is part of the at
CTAN available \texttt{mdwtools}. remember that the indented lines
in option 2 are not indented in dvi-output! the two ctrl-enter are
important!

\begin{enumerate}
\item Option 1 with any bla bla bla bla text
\item Option 2 with any bla bla bla bla text\suspend{enumerate} 
bla bla bla bla bla text ... you can write what you want. \\
the next item has the right number.\resume{enumerate}
\item Option 3 with any bla bla bla bla text
\item Same is possible without blag blah blah  without blag blah blah 


\suspend{enumerate} 

\begin{itemize}
\item The \verb/\suspend{enumerate}/-command must be in the same environment
depth as the following items.
\item Write your text or list as you like: \\
blah blah blajh blubber blah blah blajh blubber blah blah blajh blubber 
blah blah blajh blubber 


\begin{itemize}
\item and this is an itemized with a new depth
\item the next item
\end{itemize}
\end{itemize}
